Abstract:

This diploma thesis deals with identification of bacteria which are capable of producing polyhydroxyalkanoates (PHAs). Work included testing variety of genera including Pseudomonas, Lactobacillus, Bifidobacterium, thermophilic cultures and samples gathered from natural sources. Bacteria were investigated by molecular technique polymerase chain reaction – PCR. An amplification of the PHA synthase gene (phaC) was analyzed. In the first reaction phaC and 16S rRNA genes were tested at the same time. 16S rRNA gene is used as control for bacterial DNA and as an identification tool for natural source

Abstract:

This masters's thesis contains description of designed and implemented tool for classification of plant microRNA without genome. Properties of mature and star sequences in microRNA duplexes are used. Implemented method is based on clustering of RNA sequences (with CD-HIT) to mainly reduce their count. Selected representants from each clusters are classified using support vector machine. Performance of classification is more than 96% (based on cross-validation method using the training data).

Molecular biology and genetics are currently very fast developing disciplines. One of the possibilities how to increase the pupils' interest in studying of molecular biology and genetics, and to support their own curiosity is to use research-based teaching strategies. Although Czech Education tries to correspond with this progress, teaching of molecular biology and genetics is limited not only by financial and material limits but also by a lack of vocational education.

The aim of this study is to prepare and verify a molecular biological teaching cycle. This cycle is focused on hands-on activities, critical thinking and student's activity. A total of 99 pupils from two elementary schools (9th grade) and one multi-year grammar school (equivalent to primary schools) participated in the verification. They helped to create an attractive learning cycle from molecular biology, which can be used directly without major modifications and low cost.

Teaching of cell and molecular biology is often restricted by financial and material limitations as well as a lack of expertise. These problems may be overcome by cooperation with scientific institutions and universities. Some scientists teach select courses under the auspices of high school. Others allow students to fulfill internships at their workplaces. The first aim of this thesis is to describe the characteristics of summer school, wherein the participants are integral for providing feedback on what matters most to them.

Eimeria is an apicomplexan parasite causing disease coccidiosis that is most prominent in poultry farming industry. This thesis is aimed to develop new molecular tools and resolve issues that would be a valuable contribution in the field from both research and industry perspective. Because immunity to Eimeria is strictly species- specific, it is important to know and recognize correctly all species that parasitize the host. Traditional diagnostic approaches rely on classical methods such as oocyst morphology determination under the microscope, measurement of prepatent period or in-vivo assessm

Abstract:

The abilities of fungi and bacteria to degrade simple and complex carbon compounds derived from different sources, such as root exudates, litter, soil organic matter or fungal mycelium were studied in this dissertation. Knowledge of functional traits, especially degradation abilities of fungi and bacteria, are important for deciphering the black box of microbial functioning in topsoil and thus aiding in modeling and predicting future directions of microbial communities development in face of global changes.

Abstract:

In forest ecosystems, substantial part of carbon enters soil in the form of plant litter. The decomposition of litter and soil organic matter represents an important process affecting nutrient cycling and carbon balance in soils. Fungi are considered the primary decomposers in terrestrial ecosystems due to the production of wide range of extracellular enzymes that allow them to attack the lignocellulose matrix in litter. Even if fungi represent key players in organic matter decomposition, the information about the structure and diversity of their communities is still limited and the roles of i

Abstract:

The reasons for the decline in students' interest in science have been studied for the last decades. The key question is how to stimulate this interest and motivate students and pupils to study science. Part of this thesis was testing the influence of practical courses on upper secondary school students' motivation toward studying biology. To start with, it was found out how many practical courses were taught for each biology topic at Czech upper secondary schools. Molecular biology and genetics emerged as one of the topics with the lowest number of practical courses. Therefore, molecular biol

Abstract:

This thesis presents the main methods that are used to model the time evolution of the number of molecules in a cell. Two of the main aims in cell biology are to compute first the transi- tion probability function and second the density of the invariant measure. These two problems imply a number of conditions and hence we also include the ergodic theory and theory of the invariant measure. We use two illustrative examples of the application of the previously mentioned theories. We verify the necessary and sufficient conditions for the computation of the transition probability function and the

Abstract:

During last three decades, a great effort was invested to the development of polymer conjugates of low molecular drugs with the aim to improve the specific targeting of drugs to diseased tissues, cells and organs. The main reason for this effort was the fact that high molecular weight copolymers have a favourite distribution profile in tissues and organisms. A linker between a polymer backbone and drug has very important role: it is possible to synthesize a biodegradable linker, which can be enzymatically hydrolyzed. Conversely, there is a possibility to synthesize an inert linker, resistant t

In order to study the population genetics of L. acicola, eleven polymorphic microsatellite markers were developed. In addition, mating type markers that amplify both mating type idiomorphs (MAT1-1 and MAT1-2) were designed and the protocols for their applications were optimised. Co
